Gene expression analysis is used to study regulatory gene defects in cancer and other devastating diseases, cellular responses to the environment, cell cycle variation, etc.
How It Works
When genes are expressed, the genetic information (base sequence) on DNA is first transcribed (copied) to a molecule of messenger RNA (mRNA). The mRNA molecules then leave the cell nucleus and enter the cytoplasm, where they participate in protein synthesis by specifying the particular amino acids that make up individual proteins.
